C program to find the third angle of a triangle; Through this tutorial, we will learn how to find the third angle of a triangle if two angles are given in c programs.
Programs and Algorithm to Find Third Angle of a Triangle
To find the third angle of a triangle if two angles are given in c programs:
- Algorithm to find third angle of a triangle
- C Program to Find Third Angle of a Triangle
Algorithm to find third angle of a triangle
Use the following algorithm to write a program to find the third angle of a triangle if two angles are given; as follows:
- Input two angles of triangle from user and store it in some variables.
- Compute third angle of triangle using formula
c = 180 - (a + b). - Print value of third angle i.e. print c.
C Program to Find Third Angle of a Triangle
/*
* Given two angles of a triangle, Here is the
* C program to find third angle
*/
#include <stdio.h>
#define ANGLE_SUM 180
int main() {
/* Three angles of a triangle */
float a1, a2, a3;
/*
* Take two angles as input from user
*/
printf("Enter Two Angles of a Triangle :- ");
scanf("%f %f", &a1, &a2);
/* Sum of all three angles of a triangle is 180 degrees */
a3 = ANGLE_SUM - (a1 + a2);
printf("Third Angle = %0.4f", a3);
return 0;
}
The output of the above c program; as follows:
Enter Two Angles of a Triangle :- 60 30 Third Angle = 90.0000
